Ports 27 and 28 (51 and 52) represent the 1000BASE-T ports located on the rear panel of
the Switch. These port LEDs will light two different colors for 100Mbps and 1000Mbps:
Solid Green – Link for 1000Mbps
•
Blinking Green – Activity for 1000Mbps
•
Solid Amber – Link for 100Mbps
•
Blinking Amber – Activity for 100Mbps
•
Off – Link down
•
To change the LED mode from Link/Act/Speed to PoE and vice versa, press the LED Mode
Select Button. The Link/Act/Speed LED will light solid green when selected and will shut off
when PoE is selected. Likewise, when Link/Act/Speed is selected, the PoE LED shuts off
and the Link/Act/Speed LED lights solid green.
When this LED is in PoE mode, the corresponding port LED denote different meanings:
Solid Green – Power is being used by a device connected to that port.
•
Blinking Amber – There is a power error occurring on this port.
•
Off – Power is not currently being fed through this port.
•
One row of LEDs for each port is located above the ports on the front panel. The first LED is
for the top port and the second one is for the bottom ports. These port LEDs display the
following information:
For Link/Act/Speed Mode:
Solid Green – Link for 100Mbps
•
Blinking Green – Activity for 100Mbps
•
Solid Amber – Link for 10Mbps
•
Blinking Amber – Activity for 10Mbps
•
Off – Link down
•
For PoE Mode: (DES-3828P only)
Solid Green – Power feeding (802.3af-compliant PD was detected, legacy PD
•
detected)
Blinking Amber – A blinking amber LED may signify any of the following: PoE port
•
ERROR (non-standard PD connected, Under load state according to 802.3af
(current is below I min), Overload state according to 802.3af (current is above I cut),
hardware problems preventing port operation, power budget exceeded, short
condition was detected at a port delivering power, temperature overload at the port,
succession of Underload and Overload states caused port shutdown (may be
caused by a PD's DC/DC fault)...etc.)
Off – No power feeding (no PD detected, or no connection)
•
Ports 25 and 26 (49, 50) represent the 1000BASE-T/SFP ports located on the front panel of
the Switch. These port LEDs will display the following information:
Solid Green – Link for 1000Mbps
•
Blinking Green – Activity for 1000Mbps
•
Solid Amber – Link for 100Mbps
•
Blinking Amber – Activity for 100Mbps
•
Off – Link down
•
